GLASS-MELTING FURNACE.

SPECIFICATION forming part of Letters Patent No. 347,045, dated August 10, 1886.

Application filed April 10, 1886. Serial No.198,499. (No model.)

Pennsylvania, have invented a new and useful Improvement in Glass-Melting Furnaces, of which the following is a specification. My invention consists in a melting-chamber where but one row of pots are held, and in front of each pot I provide a door large enough to pass the pot, and in each door an inspec tion-hole filled with a movable plug of fire clay, and to each pot there is a separate jet or jets of flame or' gas, said jets being regulated by a slide-valve reached from the outside. I bring the air for combustion tothe jets through a tube under the heated floor of the melting-chamber, and opposite each pot I provide a glory-hole, from which the blower takes the melted glass from pots always in the same position in the chamber.

My object is to regulate and equalize the 2 5 heating of the several pots without changing their position in the chamber, and to facilitate the removal of any one when bursted or broken, to cheapen in structure, economize in fuel, and especially to save pots from destruction by overheating. I attain these objects by the structure illustrated in the accompany ing drawings, in which- Figure 1 is a sectional end view of the melting-chamber with its coal-firing furnace at one side. Fig. 2 is a front side view of the same. Fig. 3 shows a rear view with the glory-hole E E and ends of the combustion airtubes G G. 7

Similar letters refer to similar parts through out the several views.

The chamber walls A A are a continuation of the walls B B.

O is a melting-pot.

D is the floor of the meltingchamber; E, glory-hole; F, chimney G, tube to supply air for combustion and bind the wall and floorarch.

H H is flame-tube from furnace to meltingchamber; I, grate-bars to furnace; J, wall and arch to furnace where coal is first fired'into flame before it enters the melting-chamber.

K is a main for natural gas.

L is a pipe to conduct gas to melting-chamher, where it can be substituted for the flame from the furnace, or used in connection with it. 5 5

M is the opening from the melting-chamber into chimney F. g

N is a main in the floor, running the entire length of the chamber to receive and distribute the flame or natural gas to the several jets at the pots.

O is a slide-gate over each tube to regulate the flow of flame or gas.

P is a closed door with its inspection-hole closed with plug Q.

R is hole to stir up the coal infurnace.

S is dumping-hole for feeding coal from top of furnace.

The walls, arch, floor, and doors are all made of fire-clay. v

Heretofore glass-melting furnaces have been built with chambers wide enough for three rows of pots-to wit., a row on each side and room in the center for the passage of any pot that may require removal which has to be passed in or out centrally at the end, which is often a work of great difficulty, and if any pot gets too hot or too cold it has to be moved to a new position to equalize it to proper tem- I peratu re. Chambers thus constructed require arches of great strength and cost to be flat enough to get the full benefit of the heat. I aim to remedy these defects by making my melting-chamber wide enough for only one row of pots, with a door directly in front of each pot, with a jet or jets of flame or gas, or both, to each pot, regulated by a slide valve or gate reaching through the wall and operated from the outside.

To supply air for combustion, I lay pipes in 0 the floor of the chamber, (see G,) whiclnhavthe chamber, and after filling the chamber es- ICQ capes into the chimney F at the opening M, I have a main for natural gas,

near the floor.

K, with tubes L to feed the jets at H, so that enough for only one row of pots, with umain, I can use either or both, as desired. N, for gas or flame, running from end to end My furnace is supplied with coal through under the chamber-floor, supplied with air for I 5 the dumping-holes S from the top of arch J, combustion by the pipes G, entering, said main and the fire is stirred through the holes R R, l at right angles, perforated with holes nem' Fig. 2. The grate-burs are set at an angle, so their closed ends, where they pass through the the coal tends toward the wall 13 as it eonmain N, substantially {15 described, and for suines. There is nglory-hole to each pot as the purpose specified.
